<p>Energy system for buildings using solar absorbers, heat exchangers and heat accumulators, comprise the solar absorber which has tubes or pipes (7, 8) laid to form meanders between the roofing and an insulating layer (6). The solar absorber is subdivided into at least two zones each with its own liquid circulation system. There is arranged a solid heat-accumulator below the building to which heat can be supplied or removed using embedded tubes or pipes. The heat accumulator is subdivided into at least two zones, i.e. a central zone and an outer zone each with its own liquid circulation system with tubes or pipes. During operation of the heat accumulator, liquid is supplied by way of thermally controlled valves (9, 10) from the liquid circulation system of each zone of the solar absorber firstly to the liquid circulation system of the central heat accumulator zone and, secondly to the liquid circulation system of the outer heat accumulator zone, when the temperature of the liquid from the circulation system of the respective zone is greater at least by one value ranging from 2 to 8 DEG C, preferably 2 DEG C, than the temperature of the respective solid accumulator zone. During heat removal, liquid is pumped into a heating system of the building by thermally controlled valves (29a, 29b, 29c) firstly from the liquid circulation system of the outer heat accumulator zone and, secondly, from the liquid circulation system of the central heat accumulator zone.</p> |
